Just found an old hand-written journal, dated May 1993, with my then-notes on methodologies and methodology tools. I find it interesting reading, as it refers already back then to business scenarios and Warburton, who introduced me to personas also back then in 1993.
Here is the photo of the journal entry. You probably have to be a hard-core geek to read it, but if you are, I think you will also find it interesting.
